摘要

In this study, the magnetic coercivity (H_c) of Fe/ZnO heterostructure monotonically decreased as voltage was applied. The reversibility of this effect was demonstrated by cyclically changing the bias voltage from 0 to 6-9 V; the H_c decreased 15%-20%. The H_c value exhibited the same variation whether the applied voltage was positive or negative. As thick Fe-oxide gradually formed at the interface by using direct current heating, the H_c increased and the Fe/ZnO heterostructure demonstrated a similar voltage-induced reduction of H_c.
